Handy to know

No prefix needed

If your text has no data:image/... start, the tool works out the image type from the data itself.

From APIs and CSS

Copy values straight from API responses, HTML or stylesheets, quotes and all. They are cleaned up for you.

Copy the whole string

Base64 that is cut short will not decode or will show a broken image. Make sure you have the entire value.

Frequently asked questions

Is my data uploaded anywhere?

No. The Base64 is decoded inside your browser, so nothing is sent to our servers and nothing is stored.

What can I paste into the box?

A complete Data URI, a CSS background-image: url(...) rule, an HTML img tag, or just the Base64 characters. Line breaks, spaces and quotes are removed automatically.

Which image types are supported?

PNG, JPG, GIF, WebP, SVG, BMP, ICO and AVIF, as long as your browser can display them. The type is read from the data, so the downloaded file keeps its original format.

Is the downloaded image identical to the original?

Yes. The Base64 is turned straight back into the original bytes, with no re-encoding, so there is no loss of quality.

Why do I see an error or a broken image?

Usually the Base64 is incomplete, has extra characters, or is not an image at all. Copy the entire string again, including any trailing equals signs, and check that it really is image data.
